Definitions
- the present invention relates to implantable biocompatible access devices used in connection with the delivery of medicants, and other pharmaceutical fluids into a body, or the withdrawal of fluids from the body.
- Access portals provide a convenient method to repeatedly deliver medicants to remote areas of the body without utilizing surgical procedures.
- the port is totally implantable within the body, and permits the infusion of medications, parenteral solutions, blood products, and other fluids.
- the port may also be used for blood sampling.
- Known ports typically include a chamber accessible through a self-sealing septum.
- Septums of the prior art vary in shape, from a wafer-like cylindrical block of silicone to a pre-molded septum of U.S. Patent 4,802,885 to Weeks et al.
- the pre-molded septum of U.S. Patent 4,802,885 includes opposed convex surfaces and a peripheral ledge.
- a caregiver locates the septum of the port by palpitation. Port access is accomplished by percutaneously inserting a needle, typically a non- coring needle, perpendicularly through the septum of the port and into the chamber. The drug or fluid is then administered by bolus injection or continuous infusion. Ordinarily the fluid flows through the chamber, into a catheter and finally to the site were the fluid is desired.
- a needle typically a non- coring needle
- All-metal constructions have the advantages that they maintain a septum in a self-sealing fashion after repeated percutaneous injections. Additionally, all- metal constructions, such as titanium, or stainless steel provide a port which is both biocompatible and compatible with the injected fluid.
- all-plastic ports have the advantages that they are inexpensive to construct, light in weight, and do not create an MRI artifact.
- ports constructed from plastic have the disadvantage that infused fluids may react with the plastic body of the port.
- All-plastic ports contain the disadvantage that they cannot maintain a sealing engagement with the septum after repeated percutaneous injections.
- all-plastic ports are susceptible to nicks and scratches on the interior surface by the accessing needle. These nicks and scratches could lead to nidus, blood clots, or precipitation formations.
- Efforts have been made to combine the advantages of all-metal ports with all-plastic ports.
- U.S. patent 4,802,885 to Weeks et al. a metal reservoir having a chamber sealed by a pre-formed silicone septum is jacketed by a single piece of a silicone elastomer.
- all-metal ports jacketed by a single piece of elastomer have significant shortcomings. These shortcomings include quality control problems during manufacturing, and expensive molding processes.
- a hybrid port which includes a metallic reservoir, a non-metallic cowl and a non-metallic base.
- the metallic reservoir has an open top, a closed bottom and a septum. The open top is sealed by the septum to define a chamber.
- the non-metallic cowl includes a septum opening.

- a method of using the hybrid port is also within the scope of the present invention. While it is not preferred, a caregiver may be provided with the unassembled parts of hybrid port 100. These unassembled parts would include sealed metallic reservoir 101, including outlet tube assembly 104, non- metallic outer cowl 202 and inner base 250. The caregiver would select an outer cowl having the proper outer configuration for the desired application. The caregiver then would assemble hybrid port 100, according to the description above, where outer cowl 202 and inner base 250 are connected by an interference fit or snaps. The caregiver would implant port 100 within the patient, attaching outlet tube assembly 104 to a catheter which has been previously implanted, thus allowing medicants to be delivered to the desired location.
- the present invention includes advantages of a metal port and advantages of a plastic port .
- the outer plastic construction significantly decreases the weight of the present port, as compared to all-metal ports.
- the metallic construction of the reservoir provides structure to adequately seal the septum. Additionally, by utilizing a sealed metal reservoir, the present invention provides an adequately sealed chamber which is biocompatible.
